DETAILED DESCRIPTION OF THE INVENTION

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. The figures are not necessary to scale, some features may be exaggerated to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention.

Referring particularly to the drawings, there is shown one form of liquid dispensing apparatus of this invention which is commonly referred to as an air bottle 10, which has a substantially planar platform 12. Normally the platform 12 will be constructed of plastic. Exteriorly mounted on the platform 12 are a plurality of foot pads 32. These foot pads 32 are to rest on a supporting surface, which is not shown, which would normally comprise a table. Mounted on the interior surface of the platform 12 is a plastic foam cradle 14. Resting, but not fixedly secured thereto, on the foam cradle 14 is a liquid container referred as an air bottle 16. The foam cradle 14 not only provides a nesting surface for the air bottle 16 but also assists in retaining heat or cold of a hot or cold beverage that is contained within the reservoir 24 of the air bottle 16. The air bottle 16 is deemed to be of conventional construction and is formed of an outer wall which is integrally connected to an inner wall 20. In between the outer wall 18 and the inner wall 20 is an air space 22 which is to function as a heat insulator. The air space 22 could also be filled with a material that would be intended to deter the escape of heat from within the internal chamber 24 of the air bottle 16. The internal chamber or reservoir 24 is designed to be filled or partially filled with a hot liquid 26. A typical hot liquid would be coffee or tea. It is to be understood to be within the scope of this invention that instead of a hot liquid 26 being utilized, there may be utilized a cold liquid or even a room temperature liquid. The outer wall 18 includes a protuberance 28 which is normally formed during manufacture of the air bottle 16 if it is constructed of blown glass. This protuberance 28 can be used as a positioner to abut against the foam cradle 14 and therefore inform the user that the air bottle 16 is in its proper location on the foam cradle 14.

Surrounding the air bottle 16 is a sheet material housing 30. Typically, this housing 30 will also be constructed of plastic. The housing 30 includes a hinge 34 to which is pivotally connected a sheet material lid 36. The lid 36 is pivotable as indicated by arrow 33 from the closed position to the open position, as shown in FIG. 4. Fixedly mounted against the interior surface of the lid 36 is a connecting conduit 38. The connecting conduit 38 terminates at each end in flexible connectors 40 and 42. The flexible connectors 40 and 42 function to achieve a liquid tight seal between conduit 62 and cap 90 when in the closed position and yet permit the disengagement of the connecting conduit 38 from the cap 90 and conduit 62 when in the open position. Also formed within the interior surface of the lid 36 is a hole 44. Mounted within the hole 44 is a coil spring 46. Also mounted within the hole 44 and abutting against the coil spring 46 is the inner end of a pin 48. Pin 48 has a chamfered outer end 50 and a hole 52 located intermediate the ends of the pin 48. The aft edge of the hole 52 is slanted forming a chamfer 54.

Also hingedly mounted by the hinge 34 is an inner wall 56. The inner wall 56 includes an enlarged opening 58. The inner wall 56 also includes a conduit connector 60. Connecting with the conduit connector 60 is a length of flexible conduit 62.

Typically, the conduit 62 will be of a rubber or plastic material. Integrally formed on the inner wall 56 is an upstanding wall 64. The upstanding wall 64 includes a hole 66. Also mounted on the inner wall 56 is an elongated rod 70. The rod 70 has mounted thereon a ring 68. The elongated rod 70 is mounted within an appropriate opening formed within the inner wall 56. The inner wall 56 also includes a dispensing opening 72. The elongated rod 70 terminates at its inner end in a bevel 74.

Mounted on the inner wall 56 surrounding the enlarged opening 58 is a rubber or plastic gasket 76, which is to be used to form a liquid tight seal with the air bottle 16. When the inner wall 56 is pivoted to a right angled position similar to the position shown in FIG. 4 of the drawings of the lid 36, the air bottle 16 is capable of being removed from within the housing 30. The internal chamber 24 of the air bottle 16 can then be cleaned and can be resupplied of a quantity of the hot liquid 26. The air bottle 16 would then normally be reinserted back within the housing 30 and the inner wall 56 then normally moved to the position shown in FIG. 4 of the drawings. There may be a latch (not shown) provided between the inner wall 56 and the housing 30 that is located diametrically opposite the hinge 34 and directly adjacent the elongated rod 70.

The user then is to insert within the internal chamber 24 a dispensing conduit 78. The dispensing conduit 78 includes a vertical member 80, which terminates at its lower end in a screen 82. A ball 86 is to be locatable against the seat 82 which will function to prevent reverse flow of the liquid 26 from the dispensing conduit 78 back into the internal chamber 24. Upper movement of the ball 86 is prevented by a protuberance 88. The vertical member 80 is fixedly mounted to a cap 90. Cap 90 is designed to slip through the enlarged opening 58 and fit within the access opening 92 in a snug fit manner within the air bottle 16. Included within the cap 90 is a short conduit 94. The cap 90 also includes an internal passage 96. The internal passage 96 is connected to a dispensing nozzle 98.

With the vertical member 80 inserted within the internal chamber 24, and the cap 90 snugly retained within the access opening 92, and the dispensing nozzle 98 connecting with the dispensing opening 72, the lid 36 can then be moved from the open position, shown in FIG. 4, to the closed position, as shown in FIGS. 2 and 3. When doing so, the flexible connector 42 forms a liquid-tight fit with the short conduit 94. Just prior to complete closing movement of the lid 36, the outer end 50 of the pin 48 will ride over the upstanding wall 64 until the upstanding wall 64 will come into contact with the interior surface of the lid 36. In this position, the outer end 50 will then engage with the hole 66. At this time, the lid 36 is now latched to the inner wall 56 and is fixed thereto.

When it is desired to disengage the lid 36 and move such to the open position shown in FIG. 4, the user manually applies pressure against the elongated rod 70 moving such in an upward direction and causing bevel 74 to come into contact with the chamber 54. Continual upward movement of the elongated rod 70 will cause the pin 48 to move longitudinally compressing of coil spring 46 and dislocating the outer end 50 from the hole 66. This position is shown in FIG. 3a of the drawings. Movement of the lid 36 to the open position, which is approximately ninety degrees displaced from the closed position, is then permitted, as is shown in FIG. 4. The dispensing conduit 78 can then be removed as indicated by arrow 93 from the connection with the air bottle 16.

The inner end of the flexible conduit 62 is mounted on a conduit connector 100. Conduit connector 100 has an internal passage 102, which connects by an O-ring 104 to a passage 106. Passage 106 is formed within a receiving container base 108. The passage 106 connects with a hole 110, which is formed within a flexible walled bellows 112. Typically, construction of the bellows 112 would be a rubber composition. Located directly adjacent the hole 110 but formed within the platform 12 is an air hole 114. The air hole 114 is closed by a flapper valve 116. The bellows 112 is mounted within internal chamber 118 of the receiving container base 108. Movement of the bellows 112 from the collapsed position shown in FIG. 1 to the expanded position shown in FIG. 2 will cause flapper valve 116 to be unseated and air will enter the bellows 112 through air hole 114.

Located against the upper surface of the bellows 112 is a plate 120. The plate 120 has a pair of diametrically opposed depending ears 122. To each ear 122 is mounted a pair of links 124 and 126. The outer end of the links 124 and 126 are connected to member 128 which is fixedly mounted to the receiving container base 108. The plate 120 is integrally connected to a handle 130. The handle 130 protrudes exteriorly through a slot 132 formed within the receiving container base 108.

The upper surface of the receiving container base 108 includes a resting surface 134. On the resting surface 134 there is to be located a receiving container 136. The receiving container 136, which resembles a coffee cup or mug, has a handle 138 and a receiving chamber 140. The receiving container 136 is located on the resting surface 134 which positions the receiving chamber 140 directly beneath the dispensing nozzle 98.

When the user desires to supply a consumable portion 142 of a hot liquid 26 within the receiving chamber 140, the user manually presses down on the handle 130 in the direction of arrow 144. This will cause the plate 120 to move against the bellows 112 with the plate being maintained in a horizontal position at all times due to the parallelogram linkage arrangement formed by links 124 and 126. It is to be understood that there are actually two sets of the links 124 and 126 with each pair of links 124 and 126 being connected to an ear 122. This horizontal movement of the plate 120 insures that the bellows 112 is evenly collapsed and can be totally compressed to the position shown in FIG. 3. The air that is contained within the bellows 112 is forced through the passage 106, the flexible conduit 62, through the connecting conduit 38, through the short conduit 94 and into the internal chamber 24. This pressurized air will be applied against the surface of the hot liquid 26 causing some of the hot liquid 26 to be moved past the ball 86 to within the vertical member 80 through the dispensing nozzle 98 to be then deposited within the receiving chamber 140. With each depression of the lever 130, a small quantity of the liquid 26 will be squirted into the receiving chamber 140 forming the consumable portion 142. When the consumable portion 142 achieves the desired amount, according to the individual's desires, then further depression of the lever 130 is not continued. The receiving container 136 is then to be physically separated from the resting surface 134 by grasping of the handle 138 and moving such to the desired location in order to consume the consumable portion 142 within the receiving container 136.

When it is desired to resupply more of the hot liquid 26 within the receiving container 136, the receiving container 136 is again located on the resting surface 134 and the depressing procedure of the handle 130 is to be repeated.

Numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the attendant claims attached hereto, this invention may be practiced otherwise than as specifically disclosed herein.
